Hibiscus denudatus Benth.
Paleface, Rock Hibiscus
Malvaceae (Mallow Family)
Synonym(s): Hibiscus denudatus var. involucellatus
USDA Symbol: hide
USDA Native Status: L48 (N)
Paleface or Rock Hibiscus is a small shrub, 1 1/2-3 ft. high, with tiny, fuzzy leaves which drop during periods of drought. Leaves are fine-toothed, 1-1 1/2 inches long and almost as wide. A scraggly, pale plant covered with whitish hairs. Bowl-shaped, white to pinkish-lavender flowers, more deeply colored in the center, bloom in upper leaf axils and along the ends of leafless, erect branches. Inside the pink or lavender cup of a flower stands a brush-like column of stamens and stigma.
These plants seem to have too few leaves. The delicate flowers are small for the genus and lack the flamboyance of ornamental species.
